Leviton LB200 100A 2-Pole Plug-On Circuit Breaker – Hydraulic Magnetic, 120/240 VAC, White

Overview

The Leviton LB200 is a 100A, 2-pole plug-on circuit breaker designed for 120/240 VAC panels. It pairs with Leviton load centers to deliver reliable protection while simplifying both rough-in wiring and final installation. The unit’s white finish matches many panel aesthetics, helping a clean, professional look in residential or light commercial settings.

Rough-in wiring and final installation

One hallmark of the LB200 design is that the entire Load Center can be wired at rough-in with no circuit breakers installed. All hot and neutral conductors terminate at the panel’s custom lugs, not at the breaker, which means the panel can be wired up to a near-complete state before breakers are added. When it’s time for final wiring, branch circuit breakers can be plugged-on with minimal disruption to the already-wired panel.

• Time savings during rough-in, since breakers are not in the way during early wiring stages.
• Cleaner wire routing and reduced panel clutter as lugs handle termination prior to installation.
• Flexible installation flow for new builds and panel upgrades.

Hydraulic magnetic protection

The LB200 employs hydraulic magnetic trip technology, delivering precise, predictable tripping behavior over an extended temperature range. This design helps ensure the main breaker operates as intended from -40°C to 85°C (-40°F to 185°F) without needing re-rating, supporting consistent protection in varied environments.

• Stable performance in garages, basements, or utility closets with fluctuating temperatures.
• Low-maintenance protection that aligns with typical panel lifecycles.

Operational visibility and ease of use

Color-indicated handles provide at-a-glance status, so homeowners and technicians can quickly confirm whether the circuit is ready or trip occurred. In addition, the rocker-style switch design reduces activation effort compared to traditional breakers, aiding comfortable, everyday use in dense switchgear layouts.

Specifications and compatibility

LB200 is a 100A, 2-pole device rated for 120/240 VAC and built for plug-on integration within compatible Leviton panels. This model’s white finish aligns with standard panel color schemes, ensuring a cohesive look across your electrical system.

Real-world scenarios

In new build projects, the rough-in wiring approach speeds up panel assembly. During a panel upgrade, the plug-on final installation minimizes downtime. Across commercial spaces with mixed temperature environments, hydraulic magnetic protection provides reliable trip behavior without frequent re-rating concerns.
